ProX Racing Parts M-Type Cam Chain 31.2414 — Yamaha YZ250F / YZ250FX / WR250F 2014-2024

Product Description

Protect your high-RPM four-stroke engine from costly timing slips with a premium ProX Racing Parts M-Type Cam Chain. Over hours of aggressive riding, your factory timing chain stretches, causing erratic ignition timing, slack in the tensioner, and dangerous valve clearance drops. This premium replacement timing chain delivers a heavy-duty engine rebuild solution designed to handle the elevated thermal cycles and brutal stresses of modern fuel-injected Yamaha 250cc powerplants.

Manufactured in Japan by Borg Warner—the gold standard in valvetrain components—this chain is built strictly to factory OEM specifications. It features a specialized M-type link configuration utilizing custom heat-treated pins alongside advanced pin-and-link connections for maximum tensile strength and durability. Sold each, this 98XRH2010 size, 114-link raw steel chain ensures silky-smooth operation and absolute structural stability when revving your bike to the rev limiter.

Frequently Asked Questions

Q: Is this cam chain sold as a single unit or a kit?
A: This product is sold each. You will receive one continuous, pre-joined 114-link timing chain ready for installation.

Q: Does this chain fit the reverse-cylinder design found on fuel-injected Yamahas?
A: Yes. This 114-link chain is precisely sized for the unique configuration of the reverse-head 250F, 250FX, and WR models spanning the 2014 to 2024 model years.

Q: Why is a Borg Warner manufactured chain better?
A: Borg Warner produces the highest quality valvetrain components globally. Their advanced heat treatment processes drastically reduce the rate of material stretch compared to cheaper generic aftermarket options.

Expert Pro-Tip: Whenever you drop a new cam chain into a four-stroke engine, do not cut corners by leaving a high-hour manual or automatic tensioner in place. A worn tensioner spring or worn slider guides won't apply even pressure, allowing the fresh chain to whip at high RPMs and wear prematurely. Check your lower crank sprocket teeth for any hooking or flattening, wash out all debris from the stator side cavity, and ensure you use a premium engine oil to properly lubricate the pin connections right from start-up.
